Oh well, sorry for not answering earlier, I was kinda busy.
The map is actually going very well. The terraining is like 95% done; some final touches plus our two bases and it's finished.
The core systems are 100% implemented. I've implemented hundreds of cool features for later use, things like unique multipliers for each CC, crit and crit damage reduction, always hitting attacks, triggered projectiles and different things that would be harder to explain. But I keep implementing more when needed, doing it is not that hard for me.
We've got 12 heroes and 24 items completely finished and working. We've also got like 6 hero concepts.
So actually we need some more heroes and items, some balancing and it's ready for beta!
